Compact SOT363 package

Key applications

LNB IF ampliﬁer

General-purpose low-noise wideband ampliﬁer

for frequencies up to 2.7 GHz

Our MMIC wideband ampliﬁer BGA2714 is designed to

meet the speciﬁc needs of LNB designs. It operates from

a conveniently low supply voltage with a low supply current.

Improve the performance of your LNB design with our MMIC wideband ampliﬁer BGA2714.

It delivers best-in-class performance at very low current, is small and needs very few external

components. In short, it’s the ideal 1st stage IF ampliﬁer for LNBs and other low-noise

wideband applications.

A demoboard is available to help further

simplify your design-in process

In addition, it delivers industry-leading performance with a

wide frequency range, high and ﬂat power gain and low noise.

Supplied in a compact, industry-standard SOT363 package,

it simpliﬁes system integration.

MMICs like NXP Semiconductors’ BGA2714 are smart RF

solutions that automatically compensate for temperature and

process variations. They integrate transistors, resistors and

capacitors into a single device, reducing component count

and simplify design. In fact, with the BGA2714 you need just

two coupling capacitors and an RF decoupling capacitor.
